Childhood asthma is one of the most common respiratory diseases that seriously affects the physical and mental health of children, and the prevalence and mortality of childhood asthma have been on the rise in recent years. Home care for children with bronchial asthma is a discipline, and with proper care measures, the condition will recover quickly. Even healing. Improper care. It can lead to relapse or aggravation of the disease. Therefore, it is necessary for parents of children to master some simple home care and rehabilitation measures to strengthen the management of bronchial asthma. I. Identify asthma-related allergens and avoid triggers and triggering factors The increasing number of children with asthma is greatly related to changes in factors such as environmental pollution, living room furnishings and dietary and living habits. Parents and children should identify the triggers of asthma, strengthen home care for children with asthma, remove the triggers in the environment and avoid or reduce the exposure to allergens to prevent, reduce and mitigate asthma attacks and improve the quality of life of children with asthma. Specific methods are as follows: 1. Reduce contact with airborne allergens, keep indoor air fresh, ventilate regularly, and have appropriate temperature and humidity. Room temperature should not exceed 25℃. Humidity is less than 50%. Do not smoke indoors, do not keep pets, living room without carpets, avoid contact with long plush toys, etc. Wipe the dust with a damp cloth or use a vacuum cleaner with a filter frequently. Keep the living room supplies of the affected children clean. Pillows and mattresses should be changed frequently to keep them dry and exposed to the sun frequently to prevent the breeding of mites and to carry out strict pest control. 2.Food allergy is also one of the asthma triggers. Establish a scientific diet, adjust the diet appropriately, and avoid eating a certain food once it is found and confirmed by skin allergen prick test that it does trigger an asthma attack. During an asthma attack, hairy substances such as fishy fish should be avoided, and a light diet, fresh vegetables and fruits should be the mainstay. During the remission period, the diet should be supplemented according to the physical condition of the child, cold drinks should be avoided, and a well-varied, nutritionally balanced, antioxidant-rich Mediterranean diet should be carried out to protect against croup and allergies. 3. Some medications can aggravate asthma. For example, aspirin and other non-steroidal anti-inflammatory drugs can cause severe asthma attacks, and parents should take care to avoid children taking potentially allergic drugs by mistake. Most children have pre-existing symptoms before an asthma attack, but the specific symptoms vary from person to person. Help the child and parents to recall the scene before each asthma attack, such as excessive movement, itchy nose, eyes and throat, coughing, continuous sneezing, chest tightness, rapid breathing, shortness of breath, etc. The onset of an attack after each of these symptoms is the aura of an attack. Once the aura symptoms appear, medication should be administered immediately according to the principles of asthma treatment, which is of great importance to control severe asthma attacks. If the symptoms are not relieved, you should see a specialist in time. Guidance on the correct use of medication and adherence to long-term treatment Glucocorticoids are the most effective drugs for reducing airway hyperresponsiveness and eliminating the onset of airway inflammation in children, as well as suppressing early and late asthma reactions. Due to the “hormone fear” caused by the incorrect understanding of hormones, many parents treat their children only during the exacerbation period and stop treatment after the symptoms are relieved, thus causing recurrent asthma attacks and prolonging the treatment. Therefore, the first step in the long-term treatment of asthma is to help parents establish the concept of continuous treatment. Parents should be made aware of the need for continuous treatment and maintain the necessary contact with the health care provider to jointly develop a plan for the treatment of asthma attacks and remission periods. This will enable the child with asthma to receive long-term, reasonable, adequate and effective treatment. Second, the child and parents should be taught inhalation methods and techniques, and then the child should be allowed to practice repeatedly and watch more videotapes until they are correct and effective, with the main goal of reducing symptoms and preventing recurrences. Because inhalation therapy has the characteristics of small drug dose, fast onset of action and low systemic side effects, GINA has made inhalation therapy the best route of administration in the treatment of bronchial asthma. Therefore, it is very important to master the correct method of aerosol use. Shake the aerosol well before use, ask the child to wrap the nozzle tightly around the mouth and lips, and tilt the head back slightly. First exhale forcefully and do deep and slow inhalation when the nozzle is inserted into the mouth, and press the valve while inhaling. When the quantitative drug is inhaled, pull out the nozzle immediately, close the mouth and lips tightly, and hold the breath for about lO seconds to prevent the drug from escaping. Instruct the child to rinse his or her mouth promptly after use. Avoid complications such as dry cough and prevention of oral mycotic infections caused by spraying and hoarseness caused by paralysis of the contractile muscles in the vocal cords. Children have difficulty understanding inhalation therapy, plus mild odor sensation and irritation make children reluctant to cooperate. For children under 5 years old, a storage canister can be added between their aerosol dispenser and the child’s mouth to facilitate natural breathing and better and more inhalation of the drug into the trachea and lungs to reduce aerosol deposition in the mouth and increase airway ventilation.
